Use the shortest lead length possible. Note that these components are
polarized. Install the banded end as shown in the parts diagram. Don't
worry about too much heat from your soldering iron; you will not damage
the diodes.
2. In the same manner form and
install inductors L1, 2, 3, and 4
(brown-red-gold). Keep those
lead lengths as short as possi-
ble.
3. There are also eight .001uF
disc capacitors to be installed.
Again, see the diagram for proper
placement. Install C1-C8 to the
correct "tabs" on the circuit board.
Again, keep the lead lengths as
short as possible!
WHIP ANTENNA AND ANTENNA MOUNTING BOARD INSTRUCTIONS
You will need to mount two components as well as an antenna whip to each
ANTMTG board
1. Install the 1N4148 diode on the ANTMTG circuit board in the same
manner in which you installed them on the switcher, keeping those leads
as short as possible.
2. Install the 1.2 uH coil in the proper position.
3. Repeat the steps for the remaining three circuit board assemblies.
COAXIAL CABLE PREPARATION AND ASSEMBLY
We're getting very close to the end now! It is time to install the coaxial
"jumpers" that connect the antenna switcher board to the individual antenna
assemblies. To begin our preparation, locate the length of mini coax included
with your kit.
1. Cut four 13 inch pieces
of cable to connect the
switcher to each antenna
assembly.
